The current PC I bought for this project unfortunately fall short of the single core minimum benchmark of 1500. Upon further investigation, I was looking at 1) Centroid all-in-one touch screen, 2) Centroid Intel NUC CNCPC, and 3) Intel NUC model #NUC7i3BNK. All 3 of these devices use the Intel i3-7100U processor, which also falls short on the single core minimum benchmark of 1500. According to cpubenchmark.net, the single core bench mark in 1322.

So my question, what are exactly the requirement because I don't want to have to look for another computer if in fact mine will work.

Thanks

Some PC's CPU's are upgradable. Have you checked to see if you can swap CPU's?
One other thing, it seems that any Intel CPU running at 2.9GHZ or better meets the minimum. Even a Celeron processor. That is what is running on my CNC Knee mill. Solid State Drives are cheap. 128G for well under $100

Can you expand on this? You seem to be suggesting the PC's single thread benchmark is directly related to how well the Acorn will do 3D surfacing work. This is the kind of work I am planning on doing so naturally this caught my attention. Thank you.

It is not directly related as there are many factors. We give the 1500 minimum to assure that the CPU is not a bottleneck even with Windows doing other things. A correctly set-up Windows environment (with a solid state hard drive) can perform even at 1250 with no bottleneck (the caveat being it must remain setup that way, no installing a bunch of other bloatware on top of it). The lower you go though, the more chance something will come up. Windows itself is a constantly evolving environment. It might work great today, but tomorrow it decides to run some self diagnostic at the same time as your program is running. We give the minimum CPU score to give you overhead over anything like that.

A score of 1500 and even 1250 is not a huge score for today's technology. I understand wanting to keep costs down as much as possible, but a few more dollars spend and you can save yourself a world of hassles down the road.
